Ruby Float absolute() 方法与示例

Float abs()是一个浮点类方法，它作用于浮点值并将它们转换为绝对形式。

Syntax: float.abs()

Parameter: float value which is to be converted to absolute value

Return: absolute value of the passed float value

示例 #1：

# Ruby code for abs() method
  
# Initializing value
a = -56.23333333
b = -10000.0
c = -(22 + 7.1)
  
# Printing result
puts "absolute value of a : #{a.abs}\n\n"
puts "absolute value of b : #{b.abs}\n\n"
puts "absolute value of c : #{c.abs}\n\n"

输出 ：

absolute value of a : 56.23333333

absolute value of b : 10000.0

absolute value of c : 29.1

示例 #2：

# Ruby code for abs() method
  
# Initializing value
a = -100.7 - 10.4
b = -100 * 2000.0
c = -(22 + 7.1) * 4
  
# Printing result
puts "absolute value of a : #{a.abs}\n\n"
puts "absolute value of b : #{b.abs}\n\n
puts "absolute value of c : #{c.abs}\n\n"

输出 ：

absolute value of a : 111.10000000000001

absolute value of b : 200000.0

absolute value of c : 116.4
